The relationship between the pressure drop per unit length along a smooth-walled, horizontal microfluidic channel and the variables that affect the pressure drop can be expressed by:

What precautions should you take to prevent injuries when dealing with heavy loads?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.
